摘要: The input signal can be quickly and accurately classified a descriptor generated according to the result of classification. Then, retrieved on basis classification or descriptor. A processing apparatus comprises time block splitting section 3 for an audio into blocks that are typically 1 second long, feature extracting 4 characteristic quantity 18 degrees attribute from in each vector quantizing 5 carrying out operation categorical by means quantization technique uses VQ code book 8 formed degrees. outputs label obtained as indicating reliability label. If retrieving is conducted downstream, used retrieval.
